Abstract

An apparatus (1) for depositing sheet products (39, 40) at an offset has a deposition tray (2) that can be rotated alternately by 180 degrees in opposite directions about a vertical axis (41), and is equipped with a vertically movable deposition table (34). Delimiters (19, 20), arranged symmetrically to the rotation axis (41) and parallel to one another, and extending transverse to transport direction A of the sheet products (39, 40), are provided above a top starting position of the deposition table (34). Associated with each of the delimiters (19 or 20) are pivotedly arranged holding elements (17, 33 or 18, 32), which can be placed on the sheet products (39, 40) deposited on the deposition table (34). The delimiters (19 or 20) and the associated holding elements (17, 33 or 18, 32) are each configured as horizontally displaceable assemblies (21, 22). The delimiters (19 and 20) are adjusted to a distance from the rotation axis (41) that is greater, with respect to the transport direction (A), that half the width of the sheet product (39, 40). During deposition of the sheet products (39, 40), which occurs at an acute angle (.alpha.) as far as the respective delimiter (19 or 20) serv…
